Voronoi polygons

Create Voronoi polygons for a set of points. (These are also known Thiessen polygons, and Nearest Neighbor polygons; and the technique used is referred to as Delauny triangulation.)

Keywords
spatial
Usage
voronoi(xy, ext, eps=1e-09, ...)
Arguments
xy

SpatialPoints* or two column matrix with x and y coordinates

ext

Extent. Can be used to set the corners of the rectangular window enclosing the triangulation. The default is the data range plus 10 percent. See deldir

eps

Numerical tolerance used in triangulation. See deldir
